There’s a big 3d-printing related survey over at: http://www.big-3dp-survey.com
It seems to be made by the guys from the Econolyst (http://www.econolyst.co.uk/). Really nice guys, met them at the #3DPrintShow in London.
Oh, and you can win the printer of your choice up to a value of $2.500
Took me 5 minutes to complete. Good luck
